You absolutely do not have to write your Android apps in Java. You DO need a thin bootstrap layer of Java, but with the amount of Android resources out there you don't have to write this yourself. You could make the next popular Android app and never have to touch a line of Java. The NDK allows you to write apps in C/C++. And most other popular languages have a way to interface with C, you can use them as well. I've seen Android apps written in Python, Lua, and C#. Also with things like Phonegap you can use Javascript if you so desire.
